You may need a little glue to keep the switch in place: hot glue or a dot of epoxy worked fine for us. Each key also has a reverse-mount NeoPixel pointing up through the spot where many switches would have an LED to shine through.\u003c\/p\u003e\n\u003cp\u003eA microcontroller is pre-programmed with our seesaw firmware so button presses and NeoPixel-controlling is done all over I2C. You can even connect multiple board by chaining the I2C and soldering closed the I2C address jumpers - with four jumpers you can have up to 16 of these boards on a single I2C bus. Adafruit have \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_Seesaw\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eArduino\u003c\/a\u003e and \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_CircuitPython_seesaw\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCircuitPython\/Python\u003c\/a\u003e libraries for controlling the NeoKey 1x4's so you can use any microcontroller\/computer for quick creation of a custom macropad.\u003c\/p\u003e\n\u003cp\u003eYou can also fit the breakouts onto a breadboard if you like - with two sets of breakout pads, there's plenty of flexibility for any kind of use. There are two rows of 6-pin contacts on a 0.1\" grid on both sides. Solder in both sides for mechanical stability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note, each order comes with one assembled and programmed PCB but no \u003ca href=\"\/en-eu\/products\/kailh-mechanical-switches-pack-of-12\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eswitches\u003c\/a\u003e or \u003ca href=\"\/en-eu\/products\/keycaps-for-kailh-mechanical-keyboard-switches-pack-of-16\" target=\"_blank\" rel=\"noopener noreferrer\"\u003ekeycaps\u003c\/a\u003e.\u003c\/strong\u003e Soldering is required to attach the header for breadboard use, you may also need to solder jumpers closed to connect multiple boards together.
